Chad Ochocinco's already on the rebound with a new chick ... and there's no denying it, girl's got some SERIOUS JUNK ... even compared to a random girl in the background doing stripper moves.
The video was shot a few days ago in Miami -- showing Ocho and his new lady Lauren Popeil getting touchy-feely near the beach ... and Lauren's got an ass like an onion. It makes us wanna cry.
BONUS: while Ocho cuddles up with Lauren, some random chick in the background felt it was a great time to practice her stripper moves on a pole. Gotta love Miami.
FYI -- it's been six months since Ocho's domestic violence arrest ... when he allegedly headbutted his wife Evelyn Lozada. The two have since divorced.
As for Lauren and Ocho, they jetted off to Spain Tuesday to catch yesterday's Real Madrid game ... where they posted even more cuddly photos on Instagram.
Fun fact: Lauren Popeil is the daughter of Ron Popeil ... founder of the infomercial ... known for his catchphrases "Set it and forget it!" and "But wait, there's more!"
